About Door Closers
Surface and concealed closers, Grade 1 commercial, with hold-open and delayed-action options.
Commercial door closers control how a door swings shut after being opened. Sweep speed, latching speed, back-check, and hold-open functions all keep the door operating safely on rated and non-rated openings. Grade 1 (ANSI/BHMA A156.4) is the spec for institutional and high-frequency use. We quote surface-mounted closers (most common) and concealed in-frame and floor closers, from LCN, Norton, and Dormakaba in all standard finishes.
